Ness and Nevis House needed to be re clad with a new roof and the client originally envisaged the installation of traditional solar panels to meet the required 5MWH of solar energy to satisfy targeted SAP calculations. Kalzip UK persuaded the client of the benefits of using BIPVco’s Flextron modules as a means of elegantly and efficiently meeting the desired objectives.
The 4.75 KW capacity installation is expected to yield 5.08 MWH / annum of energy.The ‘butterfly design’ of the roof with a central gutter is on a 6 degree pitch. The thin film CIGStechnology of the Flextron modules has superior low light / low pitch performance and the ‘multiple diode’ design feature ensures that any loss due to shading is limited in proportion to the shaded area. The self cleaning top surface enables the modules to be kept clean even at this slope.
